I don't use the Icons for anything. If you post code in Editor mode anyways, it does not work, the code ends up being all messed up. The names are pretty self explanatory though. It's basically just the language name. With some experimentation you could edit your post until you find something.

I only really see people using these ones here though (for the most part):

[code=brainf__k]
>+[>>,----------[>,----------]+++++[<-------->-]<[>>-<]>+[
-<+++++++[<------>-]<[>>-<]>+[
-<<[>>-<]>+[<<->>->]>
]<+++++++[<++++++>-]>>
]<++++++++[<+++++>-]<
[<]<[>>[++++++++++.>]++++++++++.[[-]<]]<]
[/code]
^^ Can I write the full unedited language name without being banned?
